WARNING
• When using compressed air, there is a danger that dirt may scatter and cause personal injury.
Always wear protective eyeglasses, dust mask, or other protective equipment.
• When removing the outer element from the air cleaner body, it is dangerous to pull it out by force.
When working in high places or where the foothold is poor, be careful not to fall because of the re-
action when pulling out the outer element.
NOTICE
• Do not clean the element before the air cleaner clogging caution lamp on the machine monitor
lights up, or the yellow piston of the dust indicator laps over the peripheral red zone (7.5 kPa,
{0.076 kg/cm
2
}).
If the element is cleaned frequently before the air cleaner clogging caution lamp on the machine
monitor lights up or the yellow piston of the dust indicator laps over the peripheral red zone
(7.5 kPa, {0.076 kg/cm
2
}), the air cleaner will not be able to display its performance fully, and the
cleaning efficiency will also go down.
In addition, during the cleaning operation, more dirt stuck to the element will fall inside the inner
element.
• If any dirt enters the engine, it can damage the engine. Be sure to stop the engine before checking,
cleaning, or servicing the air cleaner. Do not check, clean, or service the air cleaner in strong winds,
or in a dusty place.
In addition, during the cleaning operation, more dirt stuck to the element will fall inside the inner
element.
• Replace the outer element if it is cleaned 6 times repeatedly or used throughout a year. Replace the
inner element as well at the same time.
METHOD FOR CHECKING AIR CLEANER
NOTICE
The electric air cleaner clogging sensor and dust indicator are used to indicate clogging on the air
cleaner. The electric air cleaner clogging sensor indicates the cleaning timing of the air cleaner element
and the dust indicator indicates the level of clogging.
Check the dust indicator before operating the machine so that cleaning of the air cleaner element is not
required during operation.
